keep PGN data short: due to a limitation of web browsers and web servers with the URL length, only short PGN texts are allowed, usually up to four games without comments; an error message shows when the max URL length limit is exceeded, in case try removing unnecessary header tags and comments/variations or try reducing the number of games per chessboard

by default the PGN data is compressed and encoded, with characters outside the 255 characters ascii set rejected and replaced with stars "*"; this might affect some non English text and names

in case of errors in the supplied PGN data, the chessboard squares starts flashing at regular intervals to signal the exception; detailed debug information is available clicking the top left chessboard square (A8 assuming White on bottom, H1 otherwise)
